1TI PHY: DT DOCUMENTATION FOR PHYs in TI PLATFORMs
2
3OMAP CONTROL PHY
4
5Required properties:
6 - compatible: Should be one of
7 "ti,control-phy-otghs" - if it has otghs_control mailbox register as on OMAP4.
8 "ti,control-phy-usb2" - if it has Power down bit in control_dev_conf register
9 e.g. USB2_PHY on OMAP5.
10 "ti,control-phy-pipe3" - if it has DPLL and individual Rx & Tx power control
11 e.g. USB3 PHY and SATA PHY on OMAP5.
12 "ti,control-phy-usb2-dra7" - if it has power down register like USB2 PHY on
13 DRA7 platform.
14 "ti,control-phy-usb2-am437" - if it has power down register like USB2 PHY on
15 AM437 platform.
16 - reg : Address and length of the register set for the device. It contains
17 the address of "otghs_control" for control-phy-otghs or "power" register
18 for other types.
19 - reg-names: should be "otghs_control" control-phy-otghs and "power" for
20 other types.
21
22omap_control_usb: omap-control-usb@4a002300 {
23 compatible = "ti,control-phy-otghs";
24 reg = <0x4a00233c 0x4>;
25 reg-names = "otghs_control";
26};
27
28OMAP USB2 PHY
29
30Required properties:
31 - compatible: Should be "ti,omap-usb2"
32 - reg : Address and length of the register set for the device.
33 - #phy-cells: determine the number of cells that should be given in the
34 phandle while referencing this phy.
35
36Optional properties:
37 - ctrl-module : phandle of the control module used by PHY driver to power on
38 the PHY.
39
40This is usually a subnode of ocp2scp to which it is connected.
41
42usb2phy@4a0ad080 {
43 compatible = "ti,omap-usb2";
44 reg = <0x4a0ad080 0x58>;
45 ctrl-module = <&omap_control_usb>;
46 #phy-cells = <0>;
47};
48
49TI PIPE3 PHY
50
51Required properties:
52 - compatible: Should be "ti,phy-usb3" or "ti,phy-pipe3-sata".
53 "ti,omap-usb3" is deprecated.
54 - reg : Address and length of the register set for the device.
55 - reg-names: The names of the register addresses corresponding to the registers
56 filled in "reg".
57 - #phy-cells: determine the number of cells that should be given in the
58 phandle while referencing this phy.
59 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
60 clock-names.
61 - clock-names: should include:
62 * "wkupclk" - wakeup clock.
63 * "sysclk" - system clock.
64 * "refclk" - reference clock.
65
66Optional properties:
67 - ctrl-module : phandle of the control module used by PHY driver to power on
68 the PHY.
69
70This is usually a subnode of ocp2scp to which it is connected.
